The critical thing to note is that in the Torque management section, you cannot simply “max out” the settings, because this computer is Torque-based - like the GEN 5 computers of the next generation; which we will discuss more in the next section, covering the GEN 5 computers. These modules first originated in trucks and SUVs, but you will also find them in 2003 to 2005 Corvettes, as well as 2004 GTOs. NEEDED. The applications for this computer are not widespread, with the primary application being the gas powered 2500 Silverados which utilize the E78 to control an LS2 based 6.0 liter. This computer was the testbed for GM to start experimenting with the controls they would implement in the GEN 5 control modules paired with the direct injection V8 lineup. Removed Vats and took out the rear ox sensors and all purge items. I am jumping ahead, there are still no '08 E67/T43 setups that would work I don't think right? In the P01 computers, the MAF table typically reads from 1,500 to 12,000 Hertz. By looking at the Driver Demand Tables, the ECM can map the amount of Torque at a given RPM or Vehicle Speed.

It controlled LS1, LS6, LS2 engines and more; and it was used in a variety of trucks, SUVs and cars as well. This can be a problem when you have modified the engine to make more Horsepower and Torque because the system is going to continually try and fight you to bring the engines Torque output back down to a stock level. The first in the line was the P01, which was used through about 2003, with the best models denoted as an 0411, usually pronounced.

In less than three hours you get access to the powerful GM LS engine, with all the vehicle electronics including instrument cluster and meters . We have been doing a 4L80E conversion in our Holden VZ here in Australia and Chris has been and absolute gem by adding all of the parameters that we have been needing to complete this conversion. The challenge every good tuner has - and one we constantly work to overcome when teaching our students how to tune, is the variety of changes that these ECMs have experienced over the years. check out the. Conduit Dress for 4L60E/4L80E Connector - 16mm, Conduit Dress for 4L60E/4L80E Connector 13mm, 4L60E 4L65E Transmission Connector Pigtail, Wire Count: EFI 58x™ GM Gen IV E38 ECM; EFI 58x™ GM Gen IV E67 ECM; CLEARANCE; Home > Harnesses & Connectors > Automotive Connectors > Connector Pigtails. Need some help on 09 5.3 / 6L80e and e38, transmission from 6L80e to 4L80e wiring schematic diagram, If this is your first visit, be sure to PAY ATTENTION, for whatever reason, TRUCK and HIGHLIGHTED LIKE THIS, ARE WIRES THAT CAN BE REMOVED FROM PCM CONNECTORS, NOT Just like the before mentioned Virtual VE Table, HP Tuners created a Virtual Torque Editor that gives you a physical table to modify in order to change data in the system in the background.

The VE values in the table represent a ratio of how full (of air) the cylinders are, compared to their theoretical maximum.
When tuning the E38, we typically find the Virtual VE system we discussed earlier in this article as the scariest part to handle; but any of our GM courses can teach you how to handle it easily. The early E38s mirrored some of the bad habits from their E40 GEN 3 predecessor, but by 2010 the idle, fuel and spark controls were some of the best GM had created to date. Should be similar for 4.8L 6.2L applications. The 2009 Trailblazer will have the E67 ECM and it may be similar to the 2009 CTS-V E67/T43 combination. Facebook page for a lot of New Pictures & Harness Guides We accept all major credit cards, plus Paypal. In fact, to the 2019 model year, if you buy a gas powered 2500 truck, it still comes equipped with the port injection 6.0 liter, making it the last remaining non-direct injected V8 engine in GM's current line up. I am kinda waiting for someone else to do it first. Based on that number, the computer knows how long to open the fuel injectors to achieve the desired air/ fuel ratio. It models the airflow for the computer to calculate fuel. If requirements are for 4 oxygen

These computers were not phased out until 2016. This is important because there is no direct sensor on the vehicle that has the ability to measure how much Torque the engine is producing.

While P59 computers closely mirror their P01 cousins, something interesting to note is that they are one of GM's first Flex Fuel capable ECMs. The computer uses this information to calculate the correct amount of fuel required. If the GEN 5 computer you are dealing with is older than 2017, then it is an E92. The computer can then seamlessly change the fuel output and spark advance on the fly to instantly compensate for a change in Ethanol content. November 02, 2020, Tuner Horror Stories Another example is the dreaded Injector Flow Rate Limit.

The first in the line was the P01, which was used through about 2003, with the best models denoted as an 0411, usually pronounced, oh-four-eleven. 4L60E will more than likely use a T42 TCM (External to the Trans). .

Just finished a LS3/4L80E swap into a 68 Chevelle. HIGHLIGHTED LIKE THIS, ARE WIRES THAT ARE NEEDED, AND GO TO EXTERNAL CONNECTION

The 0411s are also much more robust than their "fragile" 1997-2000 predecessors which are easy to damage while writing tune files to them, rendering them permanently damaged. Requires an EFI 58x™ SBC Conversion. A PSI ECM is a great addition to your PSI Harness as they are tuned specifically for your set up! With this module came a glimpse of the future and what was to come from GM as they headed towards GEN 4 computers.

All Rights Reserved. Removed Vats and took out the rear ox sensors and all purge items. Some OS/cal pairs work better than others.

I put a 6L80e (with its T43) behind an E38 ECM with an OS designed to work with a 4L60e/T42. Below are the ECM Connectors for 2008 vortec 5.3L harness. I don't want to sound pushy because the simplicity of a th400 is also compelling but the durability of a stock 6L80 is starting to get proven and if you have to build a th400 I think the price of a 6L80 starts to get compelling. While fueling and spark control are the same for GEN 5s as they are for GEN 4s, the real difference comes in the form of calculating how much Torque it should be making and then what the computer does about that calculation. How different are the RWD vs the AWD Trailblazer SS ECM and TCM files? The problem went away after loading the correct OS into the ECM (one designed for the 6L80e). For the most part, things worked fine, but there was one big bug- the engine would go into reduced power mode every now and then. ETC. The 0411s are also much more robust than their "fragile" 1997-2000 predecessors which are easy to damage while writing tune files to them, rendering them permanently damaged. Application Procedure (E38 ECM) To apply the enhancement to your PCM please use the following procedure. [ PCM PROGRAMMING ]   With that information, the computer knows how long to open the injector to get a desired amount of fuel out of it. connect to the gas pedal. It'll work out, let us know how it goes... :cheers: I put a 6L80e (with its T43) behind an E38 ECM with an OS designed to work with a 4L60e/T42. Just finished a LS3/4L80E swap into a 68 Chevelle.
